To all whom If may concern:

Be it known that I, FERDINAND F. Bimenes, n citizen of ,the United States, residing at Akron, Chio. have invented certain new und useful ini covements in Core-Carrying Stande, or" which the following a spccication.

My present invention relatfre to improvements in means for supporting cores, upon which tires are built. and is more partie larly designed for supporting the cores with the carcass or fabric hotly of the tire applied thereto, whiie finishing stripe of rubber are being placed on the caire The invention has among others for its object to provide :i core support' which may he rendily rotated by the operator to hiring: either side of the core into position 'for manipulation without requiring the open etor to inove from one point to another.

A fin-ther oog'ect is to provide n core snpporting device which will he capnhie of lief ing moved or oscillnted upon i vertical exis and which ivili oe power driven in any pos-i tion to which it may he adjusted.

lVith these and other objects in view.' the invention includes the novei tentures oit construction .find nrrangen'ient and cond` tion of ports-hereinafter descrihed and perticnlaily defined hy' the l(ippendtxl chinos, en embodiment or the invention being illesn tmted in the accompanying drawings in which*- Figure l is ii sideeievetion, away. Fig. 2 ie e. View.

horizontal. section on line o roeiers to hi d e rotatable member '2, which i may conveniently terno a. turntable. 'Passing upward centrally throue'h the hase and into the turn-table power driven shzift 25 which may he driven from any suitable source of power Iend in env suitable manner. this shaft S serving :is

axis of rotation of the torn-table. Projecting upwardly trom one side ci the 'turd trible sind preferably from an extension thereof, which avoids the necessity of unduly enlarging` the turn-table. is o standard #i which carries nt its ripper end arms Lit. Thee arios 4 curry suitable heorinizs. in `which is journaled n horizontal @he ft 'which projec laterally from .said herirnf# over the turn Secured to the n .v

ing portion of the shaft1 is e core corrving chuck which is indicated at 6, and isiiiitiend" ed to be representative of the ordinerv or any desired form of chuck, its position on the being such that the axis of the tnrntable will lie in the vertical plane. of the core carriedby the chuck. F rom this arrangement it will be seen thatby merely rotating the turn-table with its supporting standard, the core meyhe turned to bring either side or the peripheryv thereof into coiivenient nosition for the operator without requiring the hitter to change his position. This also en- `cibles the core to he reversed Without changiing its alinement with any mechanism which may he located adjacent thereto for opemtA ing upon the tire being formed on saidY core.

For locking the turntable in any position to vijhich it Ymay bri-adjusted, I provide a locl "r holt or pin 7 connected to a foot lever 5l. i ed to lng proiecting from the-base.V

:is indicated :it 9, and normally pressed up `.verd hy n springl 10 to cause said pin to engage in any one of the series or' recesses orined in the bottoni plate of the turntable.

For rotating the chuck and core without regard to any position in which it may he' adjusted. provide suitable operating connections extending np through the standard i, which is inode hollow for this purpose. finch operating connections, in the forni shown. comprise a sprocket wheel llwfai'ste on shaft 3 within the tnrntzihie und Conanted hy n sprocket chain "i2 with n sprocket l fest on vertical shaft il, iournnled in suitable hearings in the standard. This shaft 14 carries :it its upper end a beveled gen1' l5, meshing with n second beveled gene; 16 fast on the shaft 5.

ln order that the operator may control the. movement or' the shaft 3. to enable the core to he driven or stopped :it will :md when stopped to he rotated hy hond when desired. l interpose between the shaft 3 and its source of power n clutch. This muy ccnveniently he effected h v providing,r the shaft 3 with e clutch n'icxnoer i7. fast thereon :1nd providing in `iine with this, n power driven shaft E31 to which is Splined :i second clutch meinher 19. designed to he operated hv thil fork of :i clutch lever 20. Such lever muy he nornmllv piaceri under the tension of :i spring 21. operating to disengnge the clutch. and Suid clutch ineinher 19 may he moved into position to engage clutch member 17 by a treadle placed in position convenient for operation by the footofthe operator and having a notch adapted to be engaged, by a slight lateral movement of the treadle. with a dog 23, affixed to the floor or oase of the machine.

In order to ta ke up any slack in the chain. l provideA an idle sprocket 24, meshing with the chain and carried by an arm 25, pivoted uponI a pivot pin 2G, carried by the turntable, this arm having a projecting portion 2'?. provided with a fork to embrace a bolt i8, on which is threaded a knot 29 to bear against the fork portion of said projection.

In the drawings l' have shown shaft 18 as driven through bevel gears 30 and 31 from shaft 32, which latter may be driven in any suitable manner and in either Adirection at any desired speed.

If desired, the means for reversing the direction rotation of the core may be applied in connection with shaft 5 oy providing an additional bevel gear opposed to gear l@ and meshing with gear 15 and providingr s lit-able clutch mechanism for alternately connecting gear l() or the' opposing gear to said shaft. v

'Iaving thus described my invention, what I claim is:-

l. tire core carrying chuck, mounted to rotate about a horizontal axis and also about a vertical axis, and means for rotat- 4 ing said chuck on lits horizontal axis without regard to its position on said vertical axis.

2. A tire core supporting apparatus comprising a chuck, a support therefor, upon which said el. ich is mounted to rotate about a horizontal axis said support being mounted to rotate on a vertical axis, and means operative to rotate said 'chuck in all positions of said support.

3. In combination, a base, a turn-table mounted thereon, a standard carried by said turn-table offset from the axis thereof, a core carrying chuck joarnaied in the upper end of said standard, and power means for rotating said core carrying chuck.

4. In eombinationa'a base, a turn-table mounted thereon. means for locking the turn-table to the oase at any desired position, a standard carried bylsaid turn-table offset from the-center thereof, a chuck carrying shaft journaled in horizontal hearings at the upper end of said standard and power means for rotating said shaft.

5. InV combination, a base, a hollow turntable mounted thereon, a hollow standard carried b v said turn-table, a horizontal chuck carrying shaft journaled at the upper end of said standard, al power driven Ashaft located within the turn-table with its axis coincident with the axis of the turntable, a vertical shaft within the standard connected to he driven by said first named shaft, and driving connections between the shaft and the standard and said chuck carrying shaft.

G. In combination, a base, a hollow turntable mounted thereon, a hollow standard carried by said turn-table, a horizontal 'chuck carrying shaft journaled at the upper end of said standard, a power driven shaft located within the turn-table with its axis coincident with the axis of the turn-table, a vertical shaft 'ithin the standard connected to be driven by said first named shaft, and driving coniiections between the shaft and the standard and said chuck carrying shaft, and means for connecting and disconnecting the chuck loarrying shaft with the source of power at will.

In testimony whereof, l aiiix my signa* ture.

FERDINAND FRANCIS BRUCKEE.
